WARNING: This page is about a different car, the 2010 Ford Pickup and 2010 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Do not remove the Timing Chain Locking Tool at any time during assembly. If the Timing Chain Locking Tool is removed or out of placement, the engine front cover must be removed and the engine must be retimed. For additional information, refer to TIMING DRIVE COMPONENTS .

NOTE: The timing chain must be installed in its original position onto the camshaft phaser and sprocket using the scribed marks, or damage to valves and pistons will result.

NOTE: If replacement of the camshaft phaser and sprocket is necessary, transfer the scribe mark to the new camshaft phaser and sprocket.
